OPERATOR’S MANUAL
STEP 1: Check engine oil level. Oil level should be
level with the bottom of the oil filler neck. Be sure the
machine is level when checking the oil level. (Refer to
the engine's operating manual included with machine.)
We recommend that the oil be changed after the first 5
hours of use, then once every 50 hours. Note: Improper
oil levels will cause low oil sensor to shut off engine.
IMPORTANT! Do not run engine with high or low oil
levels as this will cause engine damage.
STEP 2: Remove shipping cap and install oil dipstick.
Check pump oil level by using dipstick or observe oil
level in oil window (if equipped). Use 30 wt. (non
detergent) oil.
STEP 5: Rotate the fuel shut-off valve to the "On"
position. Slide the fuel valve lever to the "ON" position.
When the engine is not in use, leave the fuel valve in
the "OFF" position.
STEP 4: Trigger the spray gun to eliminate trapped air
then wait for a steady flow of water to emerge from
the spray nozzle.
OPERATING INSTRUCTIONS
STEP 3: Fill gas tank with unleaded gasoline. Do not
use leaded gasoline.
STEP 6: Move the choke lever to the "Choke" posi-
tion (on a warm engine, leave the choke lever in the

PRESSURE WASHER
OPERATOR’S MANUAL
WARNING: Some detergents
may be harmful if inhaled or
ingested, causing severe nau-
sea, fainting or poisoning. The
harmful elements may cause
property damage or severe
injury.
STEP 1: Connect detergent injec-
tor to discharge nipple on machine.
Connect high pressure hose to injector with quick
coupler. (Check to make sure locking coupler sleeves
are in proper position before applying water pressure).
STEP 2: Use detergent designed
specifically for pressure washers.
Prepare detergent solution as
required by the manufacturer. Fill
a container with pressure washer
detergent. Place the filter end of
detergent suction tube into the
detergent container.
STEP 3: With safety latch on
spray gun engaged, secure black
detergent nozzle into quick cou-
pler. NOTE: Detergent cannot be
applied using red, yellow, green or
white nozzles.
STEP 4: With the engine running,
pull trigger to operate machine. Liquid detergent is
drawn into the machine and mixed with water. Apply
detergent to work area. Do not allow detergent to dry
on surface.
IMPORTANT: You must ush the detergent injec-
tion system after each use by placing the suction
tubeinto a bucket of clean water, then run the pres-
sure washer in low pressure for 1-2 minutes.
THERMAL PUMP PROTECTION
If you run the engine on your pressure washer for 1-2
minutes without pressing the trigger on the spray gun,
circulating water in the pump can reach high tempera-
tures. When the water reaches this temperature, the
pump protector engages and cools the pump by dis-
charging the warm water onto the ground.This thermal
device prevents internal damage to the pump.
CLEANING TIPS
Pre-rinse cleaning surface with fresh water. Place de-
tergent suction tube directly into cleaning solution and
apply to surface at low pressure (for best results, limit
your work area to sections approximately 6 feet square
and always apply detergent from bottom to top). Allow
detergent to remain on surface 1-3 minutes. Do not al-
low detergent to dry on surface. If surface appears to
be drying, simply wet down surface with fresh water.
If needed, use brush to remove stubborn dirt. Rinse
at high pressure from top to bottom in an even sweep-
ing motion keeping the spray nozzle approximately
1 foot from cleaning surface. Use overlapping strokes
as you clean and rinse any surface. For best surface
cleaning action spray at a slight angle.
Recommendations:
 • Before cleaning any surface, an inconspicuous
area should be cleaned to test spray pattern and
distance for maximum cleaning results.
 •If paintedsurfacesarepeelingorchipping, use
extreme caution as pressure washer may remove
the loose paint from the surface.
 •Keepthespraynozzleasafedistancefromthe
surface you plan to clean. High pressure wash a
small area, then check the surface for damage. If
no damage is found, continue to pressure wash-
ing.
CAUTION - Never use:

These chemicals will harm the machine and will dam-
age the surface being cleaned.
RINSING
It will take a few seconds for the detergent to clear.
Apply safety latch to spray gun. Remove black soap
nozzle from the quick coupler. Select and install the
desired high pressure nozzle. NOTE: You can also stop

SHUTTING DOWN AND CLEAN-UP
STEP 1: Remove detergent suc-
tion tube from container and insert
into one gallon of fresh water. Slide
nozzle forward for low pressure or
to connect black detergent nozzle.
Pull trigger on spray gun and siphon
water for one minute.
STEP 2: Turn off the engine. STEP 3: Turn off water
supply.
STEP 5: Disconnect the garden
hose from the water inlet on the
machine.
STEP 6: Disconnect the high
pressure hose from pump dis-
charge nipple.
STEP 7: Engage
the spray gun safe-
ty lock.
STEP 4: Press trig-
ger to release water
pressure.
CAUTION: Always store your pressure washer in a
location where the temperature will not fall below
32°F (0°C). The pump in this machine is susceptible
to permanent damage if frozen. FREEZE DAMAGE
IS NOT COVERED BY WARRANTY.
1. Stop the pressure washer, squeeze spray gun trig-
ger to release pressure.
2. Detach water supply hose and high pressure
hose.
3. Turn on the machine for a few seconds, until re-
maining water exits. Turn engine off immediately.
4. Drain the gas from the engine.
5. Do not allow high pressure hose to become
kinked.
6. Store the machine and accessories in a room which
does not reach freezing temperatures.
CAUTION: Failure to follow the above directions will
result in damage to your pressure washer.
When the pressure washer is not being operated or is
being stored for more than one month, follow these
instructions:
1. Replenish engine oil to upper level.
2. Drain gasoline from fuel tank, fuel line, fuel valve
and carburetor.
3. Pour about one teaspoon of engine oil through
the spark plug hole, pull the starter grip several
times and replace the plug. Then pull the starter
grip slowly until you feel increased pressure which
indicates the piston is on its compression stroke and
leave it in that position. This closes both the intake
and exhaust valves to prevent rusting of cylinder.
4. Cover the pressure washer and store in a clean, dry
place that is well ventilated away from open flame
or sparks. NOTE: The use of a fuel additive, such
as STA-BIL®, or an equivalent, will minimize the
formulation of fuel deposits during shortage. Such
additives may be added to the gasoline in the fuel
tank of the engine, or to the gasolinee in a storage
container.
After Extended Storage
CAUTION: Prior to restarting, thaw out any pos-
sible ice from pressure washer hoses, spray gun
or wand.
Engine Maintenance
During the winter months, rare atmosheric
conditions may develop which will cause an
icing condition in the carburetor. If this develops, the
engine may run rough, lose power and may stall. This
temporary condition can be overcome by deflecting some
of the hot air from the engine over the carburetor area.
NOTE: Refer to the engine manufacturer's manual for
service and maintenance of the engine.

HOTSY LIMITED NEW PRODUCT WARRANTY
PRESSURE WASHERS
WHAT THIS WARRANTY COVERS
All Hotsy pressure washers are warranted by Hotsy to the original purchaser to be free from defects in materials and work-
manship under normal use, for the periods specified below. This Limited Warranty is subject to the exclusions shown below,
is calculated from the date of the original purchase, and applies to the original components only. Any parts replaced under
this warranty will assume the remainder of the part’s warranty period.
SEVEN YEAR PARTS AND ONE YEAR LABOR WARRANTY:
Components manufactured by Hotsy, such as frames, handles, top and bottom wraps, float tanks, fuel tanks, belt guards, and
internal components on the oil-end of HOTSY manufactured pumps. General, AR, Liberty, Comet and swash and wobble
plate pumps have a one year warranty. Heating coils have a five year warranty from date of original machine purchase.
ONE YEAR PARTS AND ONE YEAR LABOR WARRANTY:
All other components, excluding normal wear items as described below, will be warranted for one year on parts and
labor. Parts and labor warranty on these parts will be for one year regardless of the duration of the original component
manufacturer’s part warranty.
WARRANTY PROVIDED BY OTHER MANUFACTURERS:
Motors, generators, and engines, which are warranted by their respective manufacturers, are serviced through these manu-
facturers’ local authorized service centers. Hotsy is not authorized and has no responsibility to provide warranty service
for such components.
WHAT THIS WARRANTY DOES NOT COVER
This warranty does not cover the following items:
1. Normal wear items, such as nozzles, spray guns, discharge hoses, wands, quick couplers, seals, filters, gaskets,
O-rings, packings, pistons, pump valve assemblies, strainers, belts, brushes, relief valves, fuses, pump protec -
tors.
2. Damage or malfunctions resulting from accidents, abuse, modifications, alterations, incorrect installation, improper
servicing, failure to follow manufacturer’s maintenance instructions, or use of the equipment beyond its stated us-
age specifications as contained in the operator’s manual.
3. Damage due to freezing, chemical deterioration, scale build up, rust, corrosion, or thermal expansion.
4. Damage to components from fluctuations in electrical or water supply.
5. Normal maintenance service, including adjustments, fuel system cleaning, and clearing of obstructions.
6. Transportation to service center, field labor charges, or freight damage.
WHAT YOU MUST DO TO OBTAIN WARRANTY SERVICE
In order to obtain warranty service on items warranted by Hotsy, you must return the product to your Authorized Hotsy
Distributor, freight prepaid, with proof of purchase, within the applicable warranty period. If the product is permanently
installed, you must notify your Authorized Hotsy Distributor of the defect. Your Authorized Hotsy Distributor will file a claim
with Hotsy, who must subsequently verify the defect. In most cases, the part must be returned to Hotsy freight prepaid
with the claim. For warranty service on components warranted by other manufacturer’s, your Authorized Hotsy Distributor
can help you obtain warranty service through these manufacturers’ local authorized service centers.
LIMITATION OF LIABILITY
Hotsy’s liability for special, incidental, or consequential damages is expressly disclaimed. In no event shall Hotsy’s liability
exceed the purchase price of the product in question. Hotsy makes every effort to ensure that all illustrations and specifica-
tions are correct, however, these do not imply a warranty that the product is merchantable or fit for a particular purpose, or
that the product will actually conform to the illustrations and specifications. Our obligation under this warranty is expressly
limited at our option to the replacement or repair at a service facility or factory designated by us, of such part or parts as
inspection shall disclose to have neen defective. THE WARRANTY CONTAINED HEREIN IS IN LIEU OF ALL OTHER
WARRANTIES, EXPRESS OR IMPLIED, INCLUDING ANY IMPLIED WARRANTY OF MERCANTABILITY OR FITNESS
FOR A PARTICULAR PURPOSE ARE EXPRESSLY LIMITED TO THE DURATION OF THIS WRITTEN WARRANTY.
Hotsy does not authorize any other party, including authorized Hotsy Distributors, to make any representation or promise
on behalf of Hotsy, or to modify the terms, conditions, or limitations in any way. It is the buyer’s responsibility to ensure that
the installation and use of Hotsy products conforms to local codes. While Hotsy attempts to assure that its products meet
national codes, it cannot be responsible for how the customer chooses to use or install the product. Some states do not al-
low limitations on how long an implied warranty lasts or the exclusion or limitation of incidental or consequential damages,
so the above limitation or exclusion may not apply to you. This warranty gives you specific legal rights and you may also
have other rights which vary from state to state.
